Crouse-Hinds TP449 – Frequently Asked Questions

1) Will a 4 inch square box with a VMS bracket work for new construction where the box has to sit behind drywall?
The Crouse-Hinds 4 inch steel square box with the VMS bracket is a stud-mount box, and the VMS bracket is what fixes it to the framing member before the wall goes up. If your drywall thickness means the box has to sit proud of the stud face, the same box is also sold with an "F" set-flush bracket, MPN TP446. Order the bracket style to match how you are setting the box, because the bracket is not field-swappable.
2) How many wires can I put in a 22 cubic inch 4 inch square box?
Capacity is 22 cubic inches, which is the working number for the NEC box fill calculation. Deduct for the device, the clamps, and the grounds the same way you would on any box, then divide the remainder by the per-conductor volume for the gauge you are pulling. The box carries integral NM clamps, so the clamp deduction applies whether or not you use them.
3) Do I need cable connectors with this Crouse-Hinds square box, or are clamps built in?
NM clamps are built into the box, so you land Romex directly without buying separate NM connectors. There are 4 cable knockouts for those entries plus (1) 1/2 inch bottom knockout. If you are running EMT or MC into this box instead of NM cable, you will need the appropriate connector at that knockout, since the integral clamps are for non-metallic cable.
4) What is the depth on the Crouse-Hinds 4 inch square outlet box, and will a deep device fit?
Depth is 1-1/2 inches, which is the shallow end of the 4 inch square family. The box measures 4 inches wide by 4 inches on the length/depth dimension with a 1.5 inch height. A 1-1/2 inch deep box handles standard switches and receptacles behind a plaster ring, but a bulky device such as a dimmer or a device with a large body plus several NM cables will crowd 22 cubic inches fast. For those, step up to a 2-1/8 inch deep 4 inch square box.
5) Do I get a cover or mud ring with a 4 inch square box, or do I order that separately?
The Crouse-Hinds 4 inch square box ships as the box with its bracket and integral NM clamps. A 4 inch square box has no device mounting ears in the box itself, so to hang a switch or receptacle you order a separate 4 inch square plaster ring (mud ring) in the raise that matches your wall finish, or a flat blank cover for a junction box use. Size the ring raise to your drywall thickness.
6) Can I use a 4 inch square box as a junction box for splices only?
Yes, and the 22 cubic inch capacity is a common choice for that. With 4 cable knockouts plus the 1/2 inch bottom knockout you can bring several NM runs in on the integral clamps and splice them, then close it with a flat blank cover. Keep it accessible after the wall is finished, since a splice box cannot be buried.
7) What size knockout is on the bottom of the Crouse-Hinds TP44 series box?
One 1/2 inch knockout on the bottom, which takes standard 1/2 inch trade size fittings if you are bringing a conduit stub or a cable connector in from below. The other four openings on the box are cable knockouts served by the NM clamps.
